No hot water or central heating after draining the system?

[robbieee]

Hi all.

I have a worcester 24i RSF boiler. One of the valves on my radiator was leaking so i had to drain the system.

System drained then i blanked off the valve until i could get a plumber in (next week). I repressurise the system by opening the cold inlet valve. Pressurise to 1.2Bar. Now the boiler wont ignite and i hence dont get any hot water or central heating.

I tried bleeding all the radiators, still the same. Admittidly, 2 of the bleed valves were broken so i couldnt bleed them.

Is this an airlock problem in the system? Should i pressurise to say 2.5bar to expell the air from the actual boiler?

Press the ignition reset button (white one not red) but you will need to sort your rad vents out.

Yeh i think i will need to replace the bleed valves
